Examples, please? Dolphins are not above violence, but it's tough to rape without hands or weapons, you know...

I hope you transferred to another school, the next day...

"We need a Star Trek world already where humanity works together as a whole and with a unified idea to BETTER humanity as a whole..."

I thought we didn't want to break it up...?

'Merge' would be a much better word than the oft-used 'collide,' where galaxies are concerned.

And a great many smaller ones (incendiary and high explosive) on the other cities, with the same result.

Indeed. I sometimes have to work in one, even down here.

And now you know what this was about...

"It's still regulation, Admiral..."

Kind of. The Sun is turning about six hundred million tons of hydrogen into 596 million tons of helium (of both isotopes, but not equal amounts) in the Sun every second. The difference was turned into energy.

The solar system is not as delicate as you seem to think.

Mars still has enough atmosphere to keep the stuff from reaching the surface. (and no isotope of helium is going to chemically bond with anything in that atmosphere) I'd expect it would then be lost to space, soon after...

Mercury?

Until there are commercial (there's enough down here for research purposes) fusion reactors that can use it (there are various 'aneutronic' fusion ideas being pursued that don't use it), it's irrelevant. There's no market.

Um, strangely enough, they seem to come from the same part of the world. It was found (don't ask me how...I mean, how did anyone find the safe way to prepare pufferfish?) that small stones in the uteri of camels prevented conception. This was important to Arab desert caravans, as pregnant camels won't travel.

Uh, if you can push all the way into her cervix (which is the only way you'd 'hit' an IUD)...she is gong to have something to say about this, trust me.

Gimme Jonny's dad, any day...

Yes, but that's not it. The antipodal bomber would've been a larger, rocket-sled launched beast with a flat underside.

'Mass' is constant. 'Weight' depends on the gravitational field you're in.

The hell of it is, when the earliest real 'space hotels' happen, this kind of design will likely be the most practical for guests, as (internal) space will be a a premium...and if airtight and with separate life-support connections, they'll be a safe area to retreat to in the event of a major depressurization accident…
